Renaming will cause problems for saves that have barrels with the old name. Barrels created in previous versions of the mod will disappear. I'm currently about 20 hours into a game that uses this mod and when I tried renaming it deleted 20k old steam barrels from the map.
I'm not sure if there is a way to migrate a name change in a mod, but I have already tried for a couple of hours to figure it out.
It might be possible to let the name be configurable in the mod settings. I could add a dropdown for legacy names for existing bases and new names for new bases.
I'll have to try again tomorrow evening after work to see if I can find something that will work for everyone.
